The Swedish Legation in London and the Leak Problem

In July 2013, I attended a conference at Nuffield College, Oxford on Intelligence and the Neutral Countries during the First and Second World Wars. As regards Sweden, there were two contributors: Jan-Olof Grahn who spoke about Swedish SIGINT and I who spoke about the conflict which arises from the possible leakage of information to the enemy through a neutral mission situated on the territory of a belligerent and a neutral country’s own need to collect intelligence.
